[Abstract] One of the most prevalent and interfering psychosocial comorbidities of HIV infection is clinical depression (22 to 45%). For this reason, a study of a possible interaction between the nonnucleoside reverse transcriptase inhibitor nevirapine (NVP) and the tricyclic antidepressant nortriptyline (NT) was carried out. In vitro studies with rat and human hepatic microsomes showed a marked inhibition of NVP metabolism by NT being more intense in rat than in human. The extrapolation of these results to humans suggests increased NVP side effects when both drugs are coadministered, but additional in vivo human studies are required to evaluate the clinical implication of this interaction.

This protocol describes a technique for detecting and measuring the inhibition of ... [摘要] HIV感染的最普遍和干扰的心理社会共病是临床抑郁症（22％至45％）。为此，进行了非核苷逆转录酶抑制剂奈韦拉平（NVP）和三环抗抑郁药去甲替林（NT）之间可能的相互作用的研究。使用大鼠和人肝微粒体的体外研究显示在大鼠中NT比在人中更强烈的NVP代谢的显着抑制。将这些结果外推到人表明当两种药物共同给药时，NVP副作用增加，但是需要另外的体内人体研究来评价这种相互作用的临床意义。
该方案描述了检测和测量肝微粒体中去甲替林对奈韦拉平代谢的抑制的技术。

[Abstract] Thylakoids are a formation of flattened membrane vesicles and protein complexes found in cyanobacteria, algae and plants. In the chloroplasts of land plants the thylakoid membrane systems form a network of densely packed stacks called grana lamellae, which are connected by unstacked stroma lamellae. Photosystem II is mainly localized in the appressed grana region, while photosystem I and the ATP synthase complexes are enriched in the stroma lamellae. The cytochrome b₆/f complex is distributed laterally throughout both stacked and unstacked membrane regions. The photosynthetic complexes consist of integral and peripheral proteins. The first part of this protocol (A) shows how to fractionate thylakoids into grana and stroma lamellae. The second part of this ... [摘要] 类囊体是在蓝细菌，藻类和植物中发现的扁平膜囊泡和蛋白质复合物的形成。在陆地植物的叶绿体中，类囊体膜系统形成称为颗粒薄片的密集堆叠的网络，其通过未堆叠的基质薄片连接。光系统II主要定位在贴壁的颗粒区域，而光系统I和ATP合酶复合物富集基质层。细胞色素e / f 复合物横向分布在堆叠和未堆叠的膜区域。光合复合物由整合蛋白和外周蛋白组成。本协议（A）的第一部分显示如何分裂类囊体成grana和基质层。该方案的第二部分（B）显示了如何区分强疏水整合膜缔合和弱静电膜和/或膜复合物缔合。由于必须特异性检测级分中的目标蛋白，针对目的蛋白产生的特异性抗体或表达标记融合蛋白的结构组分的互补无效突变体将是非常有利的。本协议（C）的最后一部分显示，如何调查内在和外围蛋白的拓扑。该方法需要针对目标蛋白的特异性抗体。对于内在膜蛋白，需要肽特异性抗体或表位标记的形式。该方案适合于低于5kDa的低分子量蛋白质（LMW）的研究（Torabi等人，2014）。
